Detailed Description

template<class Config, template< class=NullTransporter > class InterProcessPortal>
class goby::middleware::SingleThreadApplication< Config, InterProcessPortal >

Implements an Application for a two layer middleware setup ([ intervehicle [ interprocess ] ]) based around InterVehicleForwarder without any interthread communications layer. This class isn't used directly by user applications, for that use a specific implementation, e.g. zeromq::SingleThreadApplication.

Template Parameters

Config	Configuration type
InterProcessPortal	the interprocess portal type to use (e.g. zeromq::InterProcessPortal)

Constructor & Destructor Documentation

◆ SingleThreadApplication() [1/2]

template<class Config , template< class=NullTransporter > class InterProcessPortal>

goby::middleware::SingleThreadApplication< Config, InterProcessPortal >::SingleThreadApplication ( double loop_freq_hertz = 0 )

inline

Construct the application calling loop() at the given frequency (double overload)

Parameters

loop_freq_hertz The frequency at which to attempt to call loop(), assuming the main thread isn't blocked handling transporter callbacks (e.g. subscribe callbacks). Zero or negative indicates loop() will never be called.

Definition at line 70 of file single_thread.h.

◆ SingleThreadApplication() [2/2]

template<class Config , template< class=NullTransporter > class InterProcessPortal>

goby::middleware::SingleThreadApplication< Config, InterProcessPortal >::SingleThreadApplication ( boost::units::quantity< boost::units::si::frequency > loop_freq )

inline

Construct the application calling loop() at the given frequency (boost::units overload)

Parameters

loop_freq The frequency at which to attempt to call loop(), assuming the main thread isn't blocked handling transporter callbacks (e.g. subscribe callbacks). Zero or negative indicates loop() will never be called.
